Современная аграрная экономика сталкивается с широким спектром социально-экономических вызовов, обусловленных как деятельностью человека, так и развитием отраслей, технологий и решений управления ими. Такие вызовы объективно влияют на организационно-управленческие процессы в развитии агарного сектора экономики. Одним из перспективных направлений такого развития является применение цифровых технологий. В этой связи в статье выполнен анализ сдвигов в использовании цифровых технологий в сельском хозяйстве в разрезе федеральных округов России. The modern agricultural economy faces a wide range of socio-economic challenges caused by both human activity and the development of industries, technologies and management solutions. Such challenges objectively affect organizational and managerial processes in the development of the agricultural sector of the economy. One of the promising areas of such development is the use of digital technologies. In this regard, the article analyzes the shifts in the use of digital technologies in agriculture in the context of the federal districts of Russia.
The review presents data on the history of herbariums and fungariums, their diversity and use. It is shown that in addition to the traditional value of these objects for studying the systematics, morphology, distribution of plants and fungi, new scientific directions have emerged due to the achievements of modern science such as molecular genetic approach, genotyping, next generation sequencing. This allows identifying the molecular basis of phenotypic variability, resistance to stress, create DNA banks integrated with herbarium collections. The surviving microbial pool of herbarium samples makes it possible to isolate into a pure culture representatives of the microbiota, promising in the biotechnological aspect: for biomonitoring purposes, to create biological products of directed action against plant pathogens. Antique herbarium specimens make it possible to study the ways of migration and dispersal of plants across continents as well as expansion of epiphytoties. Analysis of the chemical composition of herbarium samples shows that the content of substances and their biological activity in many plants practically does not change over a long storage period in a dried state. At the same time, both useful biologically active substances and toxins are preserved in the studied herbarium specimens.
Background. The study of the reaction of the immune system organs to the introduction of immunomodulators in nematodes is relevant for the development of treatment regimens. The purpose of the study was to examine the spleen (the organ of immunogenesis that plays an important role in the formation of immunity). In addition, the aim of the study was also to find the morphological changes of nematodes (capsules of trichinella larvae) and the features of siphatiа. Materials and methods. In the experiment, 35 white mice were used, which were divided into 5 groups of 7 animals in each group. The first and second groups were injected with 0.004 mg saline solution subcutaneously, the 3rd and 4th groups were injected with polyoxidonium at a dose of 0.004 mg/mouse, the 1st and 3rd groups were infected with trichinella larvae, the 2nd and 4th were spontaneously affected by syphilis, the 5th group served as control. Evaluation of the protective properties of polyoxidonium in laboratory models with trichinosis was carried out by determining the intensity of invasion during postmortem studies of all muscle groups of the animal and siphations by the number of eggs in perianal scrapings. Results. The study showed protective efficacy with the introduction of polyoxidonium was 99.43%, 57 ± 20 trichinella larvae / per animal were detected in the entire muscle mass, while only 72% with syphaciosis. The parenchyma of the organ of the spleen is a red-white pulp, in healthy animals the area of the red pulp was 70+5% of the area of the organ, and the white pulp was 26.5+ 5% of the mass of the organ. In animals infected with nematodes, the area of the white pulp increased dramatically to 50% of the organ area or more. Conclusion. Significant protective activity of polyoxidonium (99.43%) was established in parasitological studies, which was accompanied by an increase in the area of lymphoid tissue associated with the intestine. When studying histological preparations of the spleen, it was noted that the restructuring of the structure under the action of trichinella and siphacia antigens is of the same type: the ratio of red and white pulp, their cellular composition changes. It was found that in all infected animals, the area of the white pulp increased dramatically by more than 60% with trichinosis and up to 50% with syphacosis of the organ area or more. The final result of this thesis was using polyoxidonium, there was also a decrease in the number of eggs in the control group and changes in the number and actual distribution of trichinella larvae in various muscle groups.
